" front axle 28, see Figure The rearward movement of the lever 14 will cause the link 13 to be moved in the direction of the arrow A, in Figure 3. This movement causes the pin 12 to slide down in the slot 11 without imparting any movement to the arm 8. The movement of the pin 12 in the slot, however, causes a roller 21 carried by the pin, to contact with the cam 20 and to swing the catch 17 free of the stop 18. It will now be seen that the catch will ride over the stop and will permit the arm 8 to be swung into the dotted line position shown in Figure 3 at a slight angle forward with respect to a perpendicular to the frame of the vehicle. Durin g the movement of the arm 8 into the dotted line position, the pin 12 will travel tothe end of the slot 11 and then back to the same end it formerly occupied, although during this movement the arm will be swung through an arc of 90 degrees.

I provide means for locking the arm 8 in the dotted line position and this means is shown in Figures 3 and 3. A pair of arms 22, see also Figure 6, are pivotally secured at 23 to the arm 8 and carry a roller 24 at their free ends. One of the arms 22 is adapted to be moved by a cam 25, see Figure 3, and this cam in turn is actuated by a link 26 which connects the cam with the pin 12. The arrangement is such that the movement of the arm 8 from the full to the dotted line position shown in Figure 3 will cause the pin 12 to move in the slot 11 and to swing the arms 22 so that the roller 24 will clear the lower lip 27 of the 3, until the arm 8 is in operative position, whereupon the cam 25 will release the arms 22 and a spring 29 will cause the arms 22 to lock the arm 8 to the front axle 28. A spring 29, see Figure 3, is used for moving the cam 25 tion.

Figure clearly shows how the wheel 4 when swung into the dotted line position shown, will lift the front wheel, indicated by the dotted line 30, clear oil the ground 31, and thus permit the wheel 4 to move the front of the car laterally, as set forth in the first part of the specification.

I will now describe the mechanism associated with the wheel 5. As hereinbefore stated, the arms 8 and 9 are rigidly connected to each other by the shaft 10 and therefore a. movement of the arm 8 into operative position will likewise move the arm 9 into operative position. The arm 9 is provided with a locking arm 32 similar to the arms 22 and the arm 32 is connected to the arms 22 by a link 33, see Figure 3, an arm 34 carried by a shaft 35 mounted within the shaft 10, see Figure 4, an arm 36 on a link 37. It will be seen from this construction that the movement of the arms 22 will cause a like movement of the arm 32 and that the arm 32 will engage with the front axle 28 in the same manner as the arms 22.

back into inoperative posiby arms 8 and I found that the wheels 4 and 5 will tend to rotate as the car is lifted and that this rotation will prevent the wheels 4 and 5 from being swung into operative position. I have therefore devised a braking mechanism for the wheel 5 that will prevent the rotation thereof until the wheel is in operative position, as shown in Figure 4. Reference may be had to Figure 6 and it will be noted from this figure that the Wheel 5 has a plurality of notches 38 therein for receiving a catch 39 of a member 40 which is slidably disposed upon the arm 9. Figure 4 shows how the member 40 is carried by a spring pressed plunger 41 wnich normall Y holds the catch .39 in one of the notches 38 and thus prevents rotation of the wheel 5. The wheel 5 is locked against rotation until the arm 9 is swung into operative position. At this juncture the top of the plunger 41 will contact with the front axle" 28, see Figure 6 and will move the catch 39 out of engagement with its notch 38, thus permitting the wheel 5 to rotate. hen the lug 39 happens to fall between two of the notches 38, the application of power to the vehicle will cause the wheel to rotate until one of the notches is brought into alignment with the lug, at which time the pressure of the spring on plunger 41 carrying lug 39 causes it to engage with the notch. This locks the wheel against further rotation until the front end of the vehicle, by further application of power, has been lifted and is carried 9. The latch is now automatically disengaged and the wheel 5 again free to rotate. The notches being relatively close, the sidewise movement of the vehicle is only a matter of inches before one of them is brought into alignment with the lug.

The wheels 4 and 5 are swung into inoperative position by a coil spring 42, see Figure 2, which is disposed around the shaft 10 and is connected thereto and to the front axle 28 in the desired manner. i

From the foregoing description of the device, the operation thereof will be readily understood.

In Figure 5 I show how the supporting member 43 is secured in place and is provided with a bearing 44 for receiving the shaft 10. There are two such supporting members 43 employed with each car 1 for supporting each end of the shaft 10. A second supporting member 45 is disposed on top of thespring 46 and carries the stop member 18 and a bumper 47.

Assume that the driver of the car wishes to park in a limited space: he jockies the car until the car is approximately in the position shown in Figure 7 with respect to the curbing 48. He now moves the lever 14 rearwardly and at the same time throws the car into reverse, which causes the front of the car to be supported by the wheels 4 and 5. The novel braking mechanism for the wheel 5 already toward the curbing 48. During the movement of the lever 14 rearwardly, the catch 17 will be automatically released and the lockand to release ing arms 22 and 32 will be moved so as to clear the lip 27 and then to engage with the axle for holding the arms 8 and 9 in operative position. If there is a crown in the road, the front of the car will very likely swing toward the curbing 48, due to gravity. However, if the road is flat, the car'may be reversed and the turning of the rear wheels 3 will cause the front of the car to swing about the pivot 7.

In swinging the wheels 4 and 5 into inoperative position, the lever 14 is swung forwardly and will swing the arms 8 and 9 into the positions shown in Figure 2. The spring 42 Will aid the swinging of the arms in this direction. The lever 14: when swung forward lv will cause the pin 12 to slide in the slot 11 the arms 22 and 32 from the front axle 28. The spring 42 will swing the arm 8 into the full line position shown in Figure 3, thus permitting the spring 19 to move the catch 17 into locked position with respect to the stop 18. The roller 21 abuts against the bumper 47 when the device is in inoperative position.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes and I reserve the right to employ such changes as may come within the scope of the appended claims.
